  • F. Christian Thompson Neal L. Evenhuis and Curtis W. Sabrosky Bibliography of the Family-Group Names of Diptera
    F. Christian Thompson Neal L. Evenhuis and Curtis W. Sabrosky Bibliography of the Family-Group Names of Diptera Bibliography Thompson, F. C, Evenhuis, N. L. & Sabrosky, C. W. The following bibliography gives full references to 2,982 works cited in the catalog as well as additional ones cited within the bibliography. A concerted effort was made to examine as many of the cited references as possible in order to ensure accurate citation of authorship, date, title, and pagination. References are listed alphabetically by author and chronologically for multiple articles with the same authorship. In cases where more than one article was published by an author(s) in a particular year, a suffix letter follows the year (letters are listed alphabetically according to publication chronology). Authors' names: Names of authors are cited in the bibliography the same as they are in the text for proper association of literature citations with entries in the catalog. Because of the differing treatments of names, especially those containing articles such as "de," "del," "van," "Le," etc., these names are cross-indexed in the bibliography under the various ways in which they may be treated elsewhere. For Russian and other names in Cyrillic and other non-Latin character sets, we follow the spelling used by the authors themselves. Dates of publication: Dating of these works was obtained through various methods in order to obtain as accurate a date of publication as possible for purposes of priority in nomenclature. Dates found in the original works or by outside evidence are placed in brackets after the literature citation.

  • Syrphid Predators for Biological Control of Aphids
    Journal of Biological Control, 27(3): 151–170, 2013 Review Article Syrphid predators for biological control of aphids SUNIL JOSHI and CHANDISH R. BALLAL National Bureau of Agriculturally Important Insects, Post Bag No. 2491, H. A. Farm Post, Bellary Road, Bangalore 560 024. Corresponding author email: [email protected] ABSTRACT: The family Syrphidae is divided into three subfamilies viz., Syrphinae, Milesiinae and Microdontinae. Majority of aphidophagous syrphids belong to the subfamily Syrphinae. Most species are terrestrial, while a few species are aquatic or live in very moist situation. Among the terrestrial forms at least 25 per cent are predacious, chiefly aphidophagous. There are more than 4700 species worldwide with 312 species under 71 genera known from the Indian subcontinent. Many studies have been conducted on the biology, intrinsic rate of increase, feeding behavior and factors affecting their oviposition and techniques for their multiplication. Relatively, less importance has been given to their field evaluation and to the studies dealing with reasons tracing causes for their less effectiveness in the open field. Recently, considerable efforts have been made to enhance their effectiveness by manipulating their habitat. Development of techniques for their effective shipment and release are necessary. Release rates, stage to be released, and stage which can be stored at low temperature need to be identified. KEY WORDS: Aphids, biology, biological control, syrphids. (Article chronicle: Received: 10-08-2013; Revised: 14-08-2013; Accepted: 21-08-2013) Economic importance of aphids long lasting, and often can be implemented at little direct cost to producers and consumers. For these reasons, World over 4000 aphid species have been recorded, biological control is considered a cornerstone of many out of which 1020 are distributed in the Oriental region.

  • Phylogenetic Relationships of the Bacchine Flower Flies (Diptera
    Contributions to Zoology 89 (2020) 210-244 CTOZ brill.com/ctoz Phylogenetic relationships of the bacchine flower flies (Diptera: Syrphidae) based on molecular characters, with a description of a new species of Melanostoma (Schiner, 1860) Ximo Mengual Zoologisches Forschungsmuseum Alexander Koenig, Adenauerallee 160, 53113 Bonn, Germany [email protected] Abstract The phylogenetic relationships among the genera of the tribe Bacchini sensu lato (i.e., Syrphinae with simple, unsegmented aedeagus) were inferred using molecular evidence. The mitochondrial protein- coding gene cytochrome c oxidase subunit I (COI) and the nuclear ribosomal 28S and 18S rRNA genes for 54 bacchine taxa were analyzed using Bayesian inference and Maximum Likelihood. Among the analyzed taxa there is a new species of Melanostoma (Schiner) from Cameroon, Melanostoma janeceki Mengual, sp. nov., which is described in full. This new species has a complete metasternum without excavation, a characteristic that is not present in other species of Melanostoma, usually with an excavated meta- sternum, but it is the diagnostic character of the genus Afrostoma Skevington, Thompson & Vockeroth. Based on the phylogenetic placement of Melanostoma janeceki Mengual, sp. nov. the taxonomic status of Afrostoma as a genus is discussed and a new generic classification of Bacchini stat. rev. and Melanosto- mini stat. rev. is presented in the light of the inferred phylogeny. Results did not recover Bacchini sensu lato monophyletic, but into two groups as follows: Melanostoma and related genera, and Baccha, Platy- cheirus and related genera. Pseudoplatychirus van Doesburg is considered junior synonym of Platycheirus Le Peletier & Audinet-Serville, and Afrostoma Skevington, Thompson & Vockeroth as junior synonym of Melanostoma.

PERHAPS THE MOST conspicuous of to the earlier Cenozoic and later Mesozoic, there is associations between insects and plants is a resurgence in understanding the evolutionary pollination. Pollinating insects are typically the first history of earlier palynivore taxa (spore, prepollen and most obvious of interactions between insects and pollen consumers), which led toward pollination and plants when one encounters a montane as a mutualism (Scott et al., 1992). meadow or a tropical woodland. The complex Almost all terrestrial vascular plants have two ecological structure of insect pollinators and their opportunities during their life cycle to disperse to host plants is a central focus within the ever- new localities. These events are spore or pollen expanding discipline of plant-insect interactions. dispersal to fertilize a megagametophyte at the The relationships between plants and insects have haploid phase, and the dispersal of the fertilized, provided the empirical documentation of many diploid megagametophyte after it has been case-studies that have resulted in the formulation transformed into a seed in seed-bearing plants. of biological principles and construction of Agamic modes of plant colonization also occur, theoretical models, such as the role of foraging such as vegetative propagation through strategy on optimal plant-resource use, the disseminules including root fragments or leaves advantages of specialized versus generalized host with adventitious rootlets.

  • Phylogenetic Relationships of the Bacchine Flower Flies (Diptera
    Contributions to Zoology 89 (2020) 210-244 CTOZ brill.com/ctoz Phylogenetic relationships of the bacchine flower flies (Diptera: Syrphidae) based on molecular characters, with a description of a new species of Melanostoma (Schiner, 1860) Ximo Mengual Zoologisches Forschungsmuseum Alexander Koenig, Adenauerallee 160, 53113 Bonn, Germany [email protected] Abstract The phylogenetic relationships among the genera of the tribe Bacchini sensu lato (i.e., Syrphinae with simple, unsegmented aedeagus) were inferred using molecular evidence. The mitochondrial protein- coding gene cytochrome c oxidase subunit I (COI) and the nuclear ribosomal 28S and 18S rRNA genes for 54 bacchine taxa were analyzed using Bayesian inference and Maximum Likelihood. Among the analyzed taxa there is a new species of Melanostoma (Schiner) from Cameroon, Melanostoma janeceki Mengual, sp. nov., which is described in full. This new species has a complete metasternum without excavation, a characteristic that is not present in other species of Melanostoma, usually with an excavated meta- sternum, but it is the diagnostic character of the genus Afrostoma Skevington, Thompson & Vockeroth. Based on the phylogenetic placement of Melanostoma janeceki Mengual, sp. nov. the taxonomic status of Afrostoma as a genus is discussed and a new generic classification of Bacchini stat. rev. and Melanosto- mini stat. rev. is presented in the light of the inferred phylogeny. Results did not recover Bacchini sensu lato monophyletic, but into two groups as follows: Melanostoma and related genera, and Baccha, Platy- cheirus and related genera. Pseudoplatychirus van Doesburg is considered junior synonym of Platycheirus Le Peletier & Audinet-Serville, and Afrostoma Skevington, Thompson & Vockeroth as junior synonym of Melanostoma.
